Flagship-grade high-frequency high-pressure probeAs a common connection solution in the oscilloscope industry, the standard BNC interface is seamlessly compatible with mainstream brand equipment such as Keysight, Tektronix, and Rigol. Its bayonet-type rotary lock design effectively prevents falling off and ensures the stability and reliability of high-frequency signal transmission. |
Ground loopsFor high-frequency voltage measurements above 40MHz, it is highly recommended to use the original alligator clip for direct grounding. By eliminating the parasitic inductance and capacitance of traditional long ground circuits, this connection method significantly improves the frequency response characteristics of the system and ensures a more stable impedance of the signal transmission path. The high-frequency response optimization improves the detail restoration of the signal waveform, and accurately captures transient harmonics and rising edge distortion. |
